Network File System (NFS)

The NFS enables several nodes to access a common file system. In this process an NFS server exports a register of its local storage, which is “mounted” by several NFS clients. Access takes place as if the register were mounted locally on the client. The disadvantage of this is that each file is stored just once on the NFS server (= single storage node) and as it is accessed by more nodes so the performance declines.
